Web Dynpro For Abap Pro Controller HaveA Web Dynpro component, a Web Dynpro view, a Web Dynpro model, a Web Dynpro controller have the same semantics both for ABAP and Java.The main difference is the designtime environment, the development infrastructure and the runtime environment. The correction and transport system keeps track on all changes that are done, versions them and helps to propagate the Web Dynpro application from development to production like you would do with ordinary BSP or dynpro-based applications. Features like portal eventing can be used between applications written in ABAP or applications developed with Java. I can tell you few like WDRTESTEVENTS ( It shows how every UI elments to use ). To generate code select good old Pattern button, go to ABAP Objects Patterns and use Call method with value shown in selection screen. GETMATERIALLIST function module have importing parameter material and material group in form of range table, which represent underlying data of select option, it retrieve data from MARA table based on importing parameter and put it in exporting parameter which is table type of MARA. Screen is then; along with select option and grid is presented to user. ![]() Index Create Web Dynpro Component Service Call Map Component Controller Context to View Controller View User Interface Create Select Option Read User Input. WDRSELECTOPTIONS encapsulate all logic to build selection screen, very similar to selection screen in report, at runtime and before you can use this magic wand you need to add this lovely component to your Web Dynpro. Its like include statement or type-pools statement, if I may say so. Double click on Web Dynpro name, top node in SE80 tree structure and enter a name under Component Use, which you would like to use to refer to this component ch is WDRSELECTOPTIONS. I am using name SELECTIONSCREEN because its easy to remember that way, but you are free to use any name here. Right click on Web Dynpro node and navigate to Create, Service call. Before we can map Component Controller Context to View Context we need to define component usage. To define this click on Controller Usage button and select Component controller from popup. We need to do this because code to call function module is in component controller and that code can only work on component controller context. On the other hand we also need this data in view for display purpose. Mapping will ensure data is available in both view and component controller and data transfer will be taken care of Web Dynpro runtime. You can add UI element by right clicking on ROOTUIELEMENTCONTAINER and choosing option Add Element. Essentially we are saying to display data from MATERIALS context node into TABLE UI element. Navigate to view MAIN and go to Properties tab and add following component using Create Controller Usage button. Web Dynpro For Abap How To Generate ThisSee tips on explanation on this code and how to generate this using Web Dynpro code wizard. Double click on WDDOINIT method of view and add following code. ![]() In the end it will call method EXECUTEGETMATERIALLIST in component controller. In next section, I will explain how to use web dynpro code wizard to generate code. Most of the code above is generated using code wizard which saves a lot of time.
